My invention relates to apparatus for coating confections, cakes, or blocks of ice-cream in the making of what are commonly 'known as Eskimo pies.

5 The :object of my invention is to provide a simple and leiiicient form of apparatus by means of which confections, cakes, etc. may be coated with a dierent material, such as icingv or chocolate, and the operations carried l on so rapidly and expeditiously as to give the machine a great capacity and do away the manual labor which has heretofore lformed a large part of such coating operations in factories for the manufacture oi such l articles.

In the accompanying drawing, Fig. 1 is a longitudinal view of my improved apparatus Ypartly in section; Fig. 2 is a plan view of same; Fig. 3 is an enlarged View of the tongs and the mannerof opening same; Fig. 4 is a like view showing the tongs closed; Fig. 5 is aside Aview of the tongs; Figs. 6 and 7 show the details of the tongs-opening device; Fig.

8 is a detail of the receiving guide; and Figs.

9, 10 and 11 show a modified form of my 1nvention.

In the drawings the numeral 2. designate-s asuitable door or foundation upon which my. improved apparatus is set up. At oneend isI :J0 the frame 3 and at the other end the standard 4. Sprocketswheels 5 and 6 are mounted in said frame 3 and standard 4, res ectively. The sprocket-wheel 5 is .mounte von the driven shaft 5". A suitable sprocket-chain g5 or belt 7 of any suitable form passes around lthe sprocket-wheels 5 and 6,

guide-sheave 7a, thereby forming inclined portions in said belt.

Secured at intervals on the chain 7 are the tong-frames 8 with the downwardly extend- 9-to which'the tongs 10 are connected, the pin 11 connecting the arms of said ing arms ivot on which said tongs tongs forming the spring12 connects the open and close.

' upper ends of the tong-arms, and said spring acts normally to hold said tongs in closedposition. Stops 13 at the upper ends of said arms are adapted 'to engage the extension 9 to control the closin lmovement of said tongs,

5o said stops being adpistable for this purpose. y

v The lower arms of the tongs carry the prongs 14 which are adaptedto engage the article to be coated, and where such an article is somewhat elongated, as in' the case of a block of ice-cream 15, al pair of such grippers may be used on each arm, as clearly indicated and under the in Fig. 5. These prongs may be made of a wlre of proper rigidity, such as piano-wire, and as they are simply inserted in seats in the tongs, they may .be readily renewed from time to time as they may wear out.

The articles to be coated are delivered to y the endless belt 16 mounted on the sheaves 17 and 18, the shaft 19 of the sheave 18 being driven by a chain 20 on a sprocket 21 on the shaft 5 engaging the sprocket 22 on, the shaft 19.

Where the material to the required len th, the knife 23'is provided which is move up and down in suitable guides 24. vA lever 25 is connected tothe link 2G connected to the knife, said lever being' pivoted at 27. A link 28 connects said lever` with the arm 29 pivoted. at 30. The arm 29 carries the roller 31 which is in the path of movement of the arm 32 on the shaft 5a. .Each time the shaft 5a makes a rotation the arm 32 engages the arm 29 andand said arm is moved, and through the link 28 and lever 'the knife is lowered to cut the material. A

be coated is cut int-o asV spring 33 is connected to the lever 25 and to theframe, .said spring acting to normally hold the knife in raised position.' As the articles to be coated are carried along' by the conveyer 16 they are directed into a suitable inclined guide or support 34 which has the flaring inlet 35. This guide 34 f i l is supported on an incline, and while in this guide the tongs take hold of the article, and to provide for the opening of the tongs at this point the tongs-opener 36 is provided with the tapering portion 37 f As the tongs approach the guide 34: they are opened gradually by engaging the tapered portion 37 of the tongs-opener, and when they reach the wide portion of said opener the tongs are v opened to their full extent and in position to grasp one of the articles to be coated in the guide 34. Just as soon as the tongs leave the `openerthe spring 12 closes the tongs and the prongs engage the article at opposite sides, as indicated in Figs. 4 and 5 just before thearticle leaves article leaves the wholly by`- the chain 7.

A tank 38 is located in the depression 39" the guide 34. When the guide 34 vit is supported in the door, and said tank contains the choco- ,I late 40, or other coating material, and suitable heating apparatus may be provided 'for maintaining the chocolate to proper consistenc for coating. The article is carried throng 1 the bath, and when it emerges thereno i spring-'arm 44 which is secured by the rivet y 45 to the belt 7. This arm has the gripping l fingers or prongs 46. The guide 47 receives the article to be coated,l as before, and thev from it continues to move along, and during this movement thecoating material is cooled and hardens around the article, s'o-that'when the article reaches the conveyer 41 it is ready to be released from .the tongs and dropped on said conveyer to be carried 'o' to the wrappers. VAccordingly at this point a tongsopener 42 is located which opens Athe tongs, and after passing said opener the tongs are then closed'until they come around'into\ p0si tion to -be o ened by the opener 36 `to' htake hold of anot er article. v l

In Figs. 9, 10 and 11 I have shown a modiI-- fied form of my invention. Instead of the carrying devices being in the form oftongs with two arms, I have illustrated a single p inner wa1l48 of said guide Aforms an abutment to support the article when the prongs 46are forced' into said article. The cam 49 in the Vpat-h of the arm 44 actsto move said' arm outwardly, and when said-arm passes beyond said cam it springsrinwardly and theA `l prongs are'forced into the'article. The sto portion 50 of the cam, 49 controls the inwar `movement of said arm and lpreventethe'distort-ingor indenting ofthe article. f

lI include within the scope of ny linvention any kind of a retaining device carried by the belt which will material.
